Electromagnetic arrangement for electromagnetic actuator in automobile, has via-hole coaxially surrounded by sleeve section that is radially arranged inside ring section to enable exact positioning of ring section during molding process

摘要

The arrangement (10) has a coil support (14) for supporting a coil arrangement. A magnetizable ring section (18) forms a part of a magnetic circuit and circumferentially molded by the support. A base section (20) is formed from a magnetic material at an axial end of the ring section. The base section forms a contact surface (22) for closing the circuit, and has a via-hole (24) coaxial to the ring section. The via-hole is coaxially surrounded by a sleeve section (26) that is radially arranged inside the ring section to enable an exact positioning of the ring section during a molding process. Independent claims are also included for the following: (1) a tool for molding a component of a magnetic top arrangement (2) a method for producing an electromagnetic arrangement.
